在1981年14号台风期间,北海船厂防波堤堤头受到了中等的损坏.本文以此为实例对扭工字块体的稳定性作了初步分析。在设计块体重量时,应考虑波浪周期问题。本文指出,根据现场观测,扭工字块体按一定模式施工的重要性。文章阐述了在计算扭工字块体的重量时,如何更好地选择稳定系数 K_D,监且强调了堤头块体应比堤身块体重0.3～0.5倍。
During the Typhoon No.14 in 1981, the breakwater embankment suffered a moderate damage to the Beihai shipyard.This article made an initial analysis of the stability of the torsion block. The wave period should be considered when designing block weights. This paper points out that according to the on-the-spot observation, the importance of constructing torsion blocks according to a certain pattern. The article elaborates how to choose the stability factor K_D better when calculating the weight of torsion block, and emphasizes that the block of head should be 0.3 ~ 0.5 times of block body weight.
